11 You, my sisters, are free from such dangers, as far as we can tell: God keep you from pride and vainglory! The devil sometimes offers counterfeits of the graces I have mentioned: this can easily be detected—the effects being exactly contrary to those of the genuine ones.148148Life, ch. xx. 31. Although I have spoken of it elsewhere,149149Found. ch. vi. I wish to warn you here of a special danger to which those who practise prayer are subject, particularly women, whose weakness of constitution makes them more liable to such mistakes. On account of their penances, prayers, and vigils, or even merely because of debility of health, some persons cannot receive spiritual consolation without being overcome by it. On feeling any interior joy, their bodies being languid and weak, they fall into a slumber—they call it spiritual sleep—which is a more advanced stage of what I have described; they think the soul shares in it as well as the body, and abandon themselves to a sort of intoxication. The more they lose self-control, the more do their feelings get possession of them, because the frame becomes more feeble. They fancy this is a trance and call it one, but I call it nonsense; it does nothing but waste their time and injure their health.
12. This state lasted with a certain person for eight hours, during which time she was neither insensible, nor had she any thought of God.150150Found. ch. vi. 15. She was cured by being made to eat and sleep well and to leave off some of her penances. Her recovery 117was owing to some one who understood her case; hitherto she had unintentionally deceived both her confessor and other people, as well as herself. I feel quite sure the devil had been at work here to serve his own ends and he was beginning to gain a great deal from it. It should be known that when God bestows such favours on the soul, although there may be languor both of mind and body, it is not shared by the soul, which feels great delight at seeing itself so near God, nor does this state ever continue for more than a very short time.151151Life ch. xviii. 16, 17. Although the soul may become absorbed again, yet, as I said, unless already feeble, the body suffers neither exhaustion nor pain. I advise any of you who experience the latter to tell the Prioress, and to divert your thoughts as much as possible from such matters. The Superior should prevent such a nun from spending more than a very few hours in prayer, and should make her eat and sleep well until her usual strength is restored, if she has lost it in this way.152152Letter of Oct. 23, 1 376. Vol. II. If the nun’s constitution is so delicate that this does not suffice, let her believe me when I tell her that God only calls her to the active life. There must be such people in monasteries: employ her in the various offices and be careful that she is never left very long alone, otherwise she will entirely lose her health. This treatment will be a great mortification to her: our Lord tests her love for Him by the way in which she bears His absence. He may be pleased, after a time, to restore her strength; if not, she will make as 118much progress, and earn as great a reward by vocal prayer and obedience as she would have done by contemplation, and perhaps more.
13. There are people, some of whom I have known, whose minds and imaginations are so active as to fancy they see whatever they think about, which is very dangerous.153153Found. ch. viii. 7-8. Perhaps I may treat of this later on, but cannot do so now. I have dwelt at length on this mansion, as I believe it to be the one most souls enter. As the natural is combined with the supernatural, the devil can do more harm here than later on, when God does not leave him so many opportunities. May God be for ever praised! Amen.
